TENPIN.

Specification of Letters Patent.

Application filed September 16, 1914. Serial No. 862,121.

ence being had therein to the accompanying drawing.

This invention relates to ten pins of the hollow type, and has for its object to provide a pin of such class, in a manner as hereinafter set forth, with interiorly arranged means for reinforcing the body of a pin whereby the denting of the pin by the balls is reduced to a minimum.

In setting up a hollow ten pin of the regulation size, the body of the pin is formed of very thin material, such as metal, fiber, celluloid, hard rubber, or other material and when constructed of thin material it is often the objection that the body becomes very easily dented when struck by the ball, but when the body is constructed of thick mate rial, the pin then is too heavy. To overcome the necessity of constructing the pin of this type, provision is made to construct the body of thin material andto have the inner face of the body provided with space, annular, spiral, or lengthwise ribs of the same material as that of which the body is formed, so that the denting of the body by the bowling balls and by contact with the alley is reduced to a minimum.

A further object of the invention is to provide a hollow ten pin, having its body, as well as its head, provided with inset portions, said inset portions forming peripheral grooves in which is arrangeda cushioning band formed of rubber, fiber, or other suitable material, the bands being in a position where the pin is generally struck by the ball andalley and by arranging the bands in a manner as stated the life of the pin is materially increased.

Further objects of the invention are to provide a metallic ten pin which is simple in its construction and arrangement, strong, unusually durable, efiicient in its use, readily set up and comparatively inexpensive.

With the foregoing and other objects in view the invention consists of a novel construction, combination and arrangement of parts as hereinafter more specifically de scribed and illustrated in the accompanying drawing wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the'claim's hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views :Figure 1 is a sectional elevation of a hollow ten 'pin in accordance with this invention. Fig.2 is a sectional detail of the bottom of the body portion. Fig. 3 is an elevation of a cap for closing the bottom. Fig. a is a sectional 'de-..

tail of a modified form of bottom. Fig. 5' is an elevation of a plug for closing the bottom shown in Fig. 1. Fig. 6 is. a. sectional view of a modified form of head cap. Fig. 7 is a modified form of neck andhead, employed in connection with form of cap shown in Fig. 6. Fig. 8 is a cross sectional view of still another modified form of head. Fig. 9 is an elevation, broken away, of a modified form of neck.

Referring to the drawings in detail 1 denotes a pin body, 2 the neck, 3 thehead and v 4: the bottom. The body 1,'neck2, and head 3 are formed in one piece and are hollow, the

material employed is preferably aluminum, but any other suitable material may be employed.

The bottom 1 has a pocket 5, which communicates with a vertically disposed opening 6 and said pocket 5, as well as said opening 6, is closed by a plug 7, which is substantially T-shaped in longitudinal section. The plug 7 is preferably constructed of fiber, but any other suitable material may be employed.

The head 3, as well as the body 1, is formed with an inset, portion of a form as illustrated at 8 and which provides a circumferential groove 9 in the head and a circumferential groove 10 in the body., The.

groove 9 has seated therein a band 11 and the groove 10 has seated therein a band 12. The bands 11, 12, project outwardly, respectively from the head 3 and body 1 and each of said bands is formed of rubber, fiber or other suitable material which has a cushioning characteristic. The band 12 is positioned where the pin is likely to be struck by a ball and the band 11 strikes the alley and under such circumstances as the bands receive the force of the blows it is obvious that the durability of the pin is increased.

When setting up a metallic ten pin of the.

regulationsize,*the body 1, neck 2- and head 3 are very thin and liable to be easily dented. by the impact of the ball. If the body 1,

neck 2 and head 3 are constructed of rather thick-materialthepinwould be too; heavy. To enable the employment of a very thin body 1, neck 2, and head 3, so that they will not be easily dented by the impact of the ball, annular reinforcing ribs are formed the neck, which' is indicated at 16, has a hollow extension 17, of less diameter than the diameter of the neck, thereby providing a shoulder 18. The extension 17 is peripherally threaded and the threads of said stem are adapted to be engaged by the interiorly arranged threads 19, of a spherical shaped head 20, which is constructed of fiber, rub her, or other suitable material. The head 20 has a flattened Lportion 21 which seats against the shoulder. 18. The neck 16 is somewhat enlarged as at 22 and the periphcry of said enlarged portion is flush with the.

flattened. portion of theliead 20.

In the modified form shown in Figs. 4, 5, the bottom is indicated at 23 and is formed of a centrally disposed opening 24, having.

the wall thereof cut away to provide a shoulderf'25, and also cut away to form a groove 26 adapted for-the reception of a plug 27 which has a head 28 and a flange 29. The plug 27 is adapted to close the opening. 24 andiwhen in suchposition the j flange 29 extendsinto the groove 26 and the head 28 seats against the shoulder 25.v The plug 27 is formed of rubber, fiberor any other suitl mater l- In the forin; shown in Figs. 6, and 7, the

neck which 'is indicated at 30 terminates in.

a head .31,- having Iperipheral 'threads33 which are e'ngagedfby an interiorlythreaded capj33,1theflattet' beingf'in the form of a band;

Copies of this 1j8tent'.:maybe obtained lfor 'five cents each, by; addressing the Commissioner of-Iatexits;

It iIlS obvious that the ribs'13 can be disposed-spirally with respect to the inner. face. of the body portion of a'pin, orth'at they. can extend lengthwise with respect to said body portion.

What weclaim is 1. A ten pin comprising a unitary-hollow.

structure including a body, neck,and head, and reinforcing ribs formed integral with the inner face of said body, neck'and head.

2. A ten pin comprising aunitary hollow 1 structure including a body, neck," and head,

triangular reinforcing ribs formed integral with the inner'face of said body, neckand head, said ribs being triangular in cross section.

tachably mounted on said neck;

4:- A ten pin formed of a unitary hollow element including a body, neck andhead,'a and annular spacedreinforcing ribs formed,

integral with. the inner faces of said head,.

neck and body, saidhea-dand said bodyhaving an inset portion forming a circumferential. groove, and bands mounted in :said.

grooves and being of different material than that of the head. and body.

5.. A ten pin comprising ahollow metallic element including abody, neck, and.-head,"' and reinforcing ribs integral with the inner' faces of said body, neck and head, and bands: seated in said body and head, said bands formed of different. material from the material of the body and head.

6., A tenpin comprising a-hollow elementformed of thin metal, and reinforcing; ribs integral with theinner faces of said element, said bodyhaving. a bottom formed with an openingand a plug for. closingsaid opening, said plug formed'of different: material from that of the body.
